Three 2.7 V/3.3 V 10-bit video DACs provide support for composite (CVBS), S-Video (YC), or component (YPrPb/RGB) analog outputs in either standard-definition (SD) or high-definition (HD) video formats. Optimized for low power operation, occupying a minimal footprint and requiring few external components, these encoders are ideally suited to portable and power sensitive applications requiring TV-Out functionality. Cable detection and DAC auto power-down features ensure that power consumption is kept to a minimum. The ADV7390/ADV7391 have an 8-bit video input port that supports SD video formats over a SDR interface and HD video formats over a DDR interface. The ADV7392/ADV7393 have a 16-bit video input port that can be configured in a variety of ways. SD RGB input is supported. All members of the family support embedded EAV/SAV timing codes, external video synchronization signals and the I2C and SPI communication protocols. Table 1 lists the video standards directly supported by the ADV739x family. Table 1.
